Students from around the world calculated their class mean and standard deviations for their footprints and posted them on our world map.
Do you see differences across the globe? If so, why do you think those differences exist?
Did you use the calculator to try to reduce your footprint down to the average from a citizen of another country? What changes would you have to make to lower your footprint in this way? Are you going to try and take some of these actions in your daily life?

Floods
Floods happen almost everywhere in the world : I think we should build embankments and more houses on high points. What do you think ?
I completely agree with you. We already can see on coast lines, like beaches where houses are built higher up to sustain a strong storm surge. In locations that are known to flood regularly we should build embankments and houses higher off the ground. This will prevent peoples homes from getting destroyed during floods and will prevent having to pay for damages due to flooding.
